GAUGE FOR LOOMS.

Application filed May 23, 1925. Serial No. 32,299.

To all whom it may concern.-

Be it known thatv I, ERNEST BAr-zeiui, a citizen of the United States, residing at Paterson, in the county of Passaic and State New Jersey, have invented certain new and useful Improvements in Gauges Looms, of which the following is a specification.

It is known to the operators of looms that certain defects in weaving occur which are due to some of the reciprocating parts, as the lay structure or the reed there-cu, not assuming accurately a given position the end of the working stroke, as by overrearhr ing or underreaching the same or being skewed with relation thereto, caused either by improper initial adjustment in setting up the loom or by the parts getting out of ad justment in time. The object of this invention is to provide means whereby "faulty adjustment of this character can be readily detected and its correction facilitated. invention is not limited in its application to looms but may be used in connection with other machines including reciprocating parts.

In the drawing, V

Fig. 1 shows in plan theforward part of a loom, with the device of my invention arranged thereon; I Fig. 2 is a vertical sectional view of said part of the loom, showingthe device in side elevation; and

Figs. 3' and 4: illustrate details.

1 designates the loom frame, which may be regarded as including the breast-beam 2, and 3 are the lay-swords and 4 the lay or batten of the lay structure which is reciprocated in the usual way through the pitmen 5 ivotally connected therewith. The lay structure is supposed to be mounted so that, at least when it is in the fully forward or beating-up position, it will also be perpendicular to the path of advance of said sheet of warp and woven goods, and this is true also of the reed suitably arranged in a re cess 4 at the back of the batten and held normally bearing against the latter by springs P, being pivoted at 3 in bracl-:ets 3 and the reed is further supposed to exert a certain amount of pressure (due to the springs) on the fell of the fabric. But defects occur frequently in weaving that are due to one or the other of the lay structure and reed being not accurately in the position it should have at the end of the working stroke. Now for detecting such irregulari- The ties and facilitating correcting them I pro vide the means hereinafter embodied in the claims and one example of which I now describe in detail:

A support is provided here consistingot a base-strip 7 and a plurality of clips 8' so cured thereon. The support is'intended in the present case to have a bearing on the forward face of the breast-bean'i and this purpose the clips 8, which may be formed of strap metal, have their forwart sure 8 bent downward so as to stand 'in a vertical plane when the support is seated on tho breast-bean'i; the clips are shown ext-ending over the base-strip and they are'at rightangles thereto (said strip being'straight),

the means to secure them to the base-stripbcing shown as screws 9. Their upper ends are re-bent to form crotches open toward the batten, the crotches having set-screws 10 arranged 'vertically and at their closed ends adjusting screws 11. i i

A gauge-including structure is carried by the mentioned support or supporting means,

the same including with the gauge a straightedge strip 12 which is received bythe crotches and stands in contact with the adusting screws and'held by the set-screws;

the straight edgeof this strip adjoins th Any suitable gaugemay be used batten.

having a movable gauge-actuator, that shown being a dynamometer of the piston and-cylinder type. 13 is its Cyl'l11l6l,'1t t piston or gauge-actuator, and 15 the case ofthe gauge-proper having a (hall? and a pointer 18 movable by pressure of a fluid contained in the gauge and admitted from the cylinder to the interior of the case by a tubular connection 16. The gauge has means to hold it in a definite position on the strip 12, as a crotch or cross-groove 19 formed in the closed end of the cylinder and fitting snugly over the inward or straight edge of said strip. r

The free end of the piston or plunger is suitably equipped to receive the impact of the reed or other moving part, and for this purpose I preferably provide it with interchangeable adapters. One such adapter, in-

tended to receive the impact of the reed dents, is a blade 20 which is held in a crossgroove 21 of the piston by a removable pin 22 so that the blade is at right-angles to the piston. Or a cap-like head (Fig. 4) may be fitted snugly over the free end of the piston, being adapted for engagement with -ward the piston.

some surface ofl'ering stouter resistance than the reed dents. Y

24: is a truss for stiffening the strip 1 In use the operator places the support in fixed position on some fixed part '01 the machine frame, as the breast-beam, usually securing it by some means, as the clamps 25 shown by broken outline in Fig. 1 as engaging the outer face of the breast-beam and the lugs 8", the strip 12 being adjusted and secured where adjusted so that its straight-edge is perpendicular to the path taken by the sheet of warp and woven fabric as it is advanced in the process of weaving. The gauge is then fitted to the support so that it abuts squarely against the straight-edge and the piston and cylinder are perpendicular tosaid edge. The desired deduction is then attained in an obvious manner by moving the partto be tested to- The operator knows, for example, that in the fully forward position ofthe batten the pressure of the reed should cause the pointer to be moved to a certain point on the scale of the gauge; it it does not adjustment of the springs t is eli'ected. Again, if the two lay-swords, or the two ends of the batten or of the reed, etc., do not at the end of the forward stroke come to the same line perpendicular to the path of advance of the sheet of warp and woven fabric this will be revealed by the gauge upon putting it in operation first at one point on the strip 12 and then at a more or less remote point.

While so far as adjustment toward and from the. part to be tested is concerned I have treated 78 as" a support or supporting means and the gauge and rail 12 as a gaugeincluding structure it will also be apparent that so far as lateral or transverse adjustment is concerned 7812 may be regarded as a carrying structure on which (along said straight-edge) the gauge is capable oi? such ad ustment.

said structure being adjustable on the sup port substantially lengthwise or" the path of movement of the reciprocating part.

3. In a means for detecting irregularity in the position of a reciprocating part relatively to a fixed part of a machine when the reciprocating part is at the limit of its worning stroke, the combination of supporting means adapted to be fixed on one such part of the machine, a straight-edge strip an ranged transverse of the path ot'reciprocation of the reciprocating part and adjustable on said means substantially lengthwise of said path, and a gauge includinga movaple gauge-actuator adapted to be engaged and moved by the other of said parts, said gauge being adjustable on said strip along said straight-edge.

In testimony whereof I aiiix my signature.
